To anyone who believes environmental regulation is poison for profits, California must be infuriating. The state’s pollution policies rarely wilt its perennially blooming economy. For the past nine years, a Golden State-centric think tank Next 10 has been releasing its California Green Innovation Index. The results this year show a continuing trend: For two and a half decades, California’s GDP and population have continued to rise, while per capita carbon dioxide emissions have stayed flat. But California isn't done yet. It has two major upcoming goals: reducing emission to to 1990 levels by 2020, and 40 percent below that a decade later. So while California has continued to grow during phase one of its environmental overhaul, it's still a question whether its long-term green ambitions will turn its economy as chilly as a San Francisco summer.
